Fairchild Semiconductor
The ABT899 is a 9-bit to 9-bit parity transceiver with transparent latches. The device can operate as a feed-through transceiver or it can generate/check parity from the 8-bit data busses in either di.
independent latch enables for the Ato-B direction and the B-to-A direction, a select pin for ODD/EVEN parity, and separate error signal output pins for checking parity. Features s Latchable transceiver with output sink of 64 mA s Option to select generate parity and check or “feed-through” data/pari.
